Ford Escort Van diesel, came out Sat morning to a completely flat battery, no ignition lights, nothing. Its a new battery, less than 6 months old and was replaced same time i fitted a new alternator. UIsed it Thurs night, then Sat dead as a dodo. Didnt leave lights on always double check.
AA man jump starts me, all ok, battery charging and no drain on battery when ignition is turned off. Go out today to check power still in battery, light up ignition lights a couple of times but dont start the engine, all lights on. Half hour later go to start her up and turns over, but not starting up. After a couple of trys i give up, dont want to drain the battery completely, turn ignition off and take keys out but the ignition lights (handbrake, oil pressure etc) stayed on, but very fiently. Someone suggested a sticky relay, someone else the ignition itself, and another a short somewhere

Any ideas?

 

Mk5/6 van by any chance?

I'm guessing it is by the symptoms, in which case it means your fuse box has gone down! very common to fail on these models, i have just recently repaired one on my friends Mk5 RS2000, definately not a fun job

 

I had the same thing happen to my mk6 van, but the only difference was it would only do it when the footbrake was applied. It turned out to be a burnt out connection on the brake light. Weird...

 

Sounds familiar
